... these words -- separate
each with a space, not a comma.
Hit return, and the search begins.
Let's say you're utterly fascinated with wheat. So you might select
agricultural-market-news to find its current world price. But you also
want to see if it has any religious implications, so you choose the
Bible and the Book of Mormon. What do you do with the stuff? Select
recipes and usenet-cookbook. Are there any recent Supreme Court
decisions involving the plant? Choose supreme-court. How about synonyms?
Try roget-thesaurus and just plain thesaurus.
Now hit w and type in wheat. Hit enter, and the WAIS program begins
its search.
As it looks, it tells you whether any of the databases are
offline, and if so, when they might be ready for a search.
In about a
minute, the program tells you how many hits it's found. Then you get a new
menu, that looks something like this:

Each of these represents an article or citing that contains the word wheat,
or some related word. Move the cursor bar (with the down and up arrow
keys) to the one you want to see, hit enter, and it will begin to appear
on your screen. The "score" is a WAIS attempt to gauge how closely the
citing matches your request. Doesn't look like the Supreme Court has had
anything to say about the plant of late!
Now think of how much time you would have spent logging onto various
databases just to find these relatively trivial examples.
8.6 THE WORLD-WIDE WEB
Developed by researchers at the database inverness European Particle Physics
Laboratory in Geneva, the World-Wide Web is somewhat similar to a WAIS.
But it's designed on a system known as hypertext. Words in one document
are "linked" to other documents. It's sort of like sitting with an
encyclopedia -- you're reading an article, see a reference that
intrigues you and so flip the pages to look up that reference.
To try the Worldwide Web, telnet to
ukanaix.cc.ukans.edu
Log on as: www. When you connect, you'll see something like:

8.7. CLIENTS, OR HOW TO SNARE database info MORE ON THE WEB
If you are used to plain-vanilla Unix or MS-DOS, then the way these
gophers and WAISs work seems quite database devon straightforward. But if you're used
to a computer with a graphical interface, such as a Macintosh, an IBM
compatible with Windows or a Next, you'll database inverness probably regard their
interfaces as somewhat primitive.
And even to a veteran MS-DOS user, the
World-Wide Web interface is database information rather clunky (and some of the documents and
files on the Web now use special formatting that would confuse your poor
computer).
There are, however, ways to integrate these services into your
graphical user interface. In fact, there are now ways to tie into the
Internet directly, rather than relying on whatever interface your
public-access system uses, through what are known as "client" programs.
These programs provide graphical interfaces for everything from ftp to
the World-Wide Web.
There is now a growing number of these "client" programs for
everything from ftp to gopher. PSI of Reston, Va., which offers
nationwide Internet access, in fact, requires its customers to use these
programs. Using protocols known as SLIP and PPP, these programs
communicate with the Net using the same basic data packets as much larger
computers online.
Beyond integration with your own computer's "desktop,'' client
programs let you do more than one thing at once on the net -- while you're
downloading a large file in one window, you can be chatting with a
friend through an Internet chat program in another.
Unfortunately, using a client program can cost a lot of money. Some
require you to be connected directly to the Internet through an Ethernet
network for example. Others work through modem protocols, such as SLIP,
but public-access sites that allow such access may charge anywhere from
$25 to $200 a month extra for the service.
Your system administrator can give you more information on setting
up one of these connections.
